InterviewReady plugin for Claude and Codex

Interview prep for software engineers from InterviewReady. It plans your preparation day by day up to your interview date, serves one question at a time near your level, and times and grades every answer on InterviewReady's server, so the score is the same in any app.

Rounds

Round	Questions	Graded by
Coding	Problems with sample and hidden test cases	Running your code against the hidden cases
System design	Reference designs from InterviewReady's system design judge, with one component hidden, and capacity estimates	The judge's own answers and bounds
Behavioural	The question bank of InterviewReady's AI mock interviewer	The mock interviewer's rubric
AI engineering	The adaptive assessment on aiengg.dev	Its answer key

Each answer sets the difficulty of the next question. A comparison with other learners appears once 30 people have answered a question.

Your data

The plugin signs in with your InterviewReady account. It stores your plan, your answers and their grades, the applications and debriefs you save, and the progress you choose to share. The skills ask before reading your resume or git history. They instruct the assistant to keep offer details in the conversation. Content submitted as an answer, application note or debrief is stored by InterviewReady. Your host app also processes the conversation under its own privacy policy. Behavioural answers are sent to OpenAI for grading; submitted code runs on InterviewReady's code runner. Ask the plugin to delete your prep data to remove its plans, answers, applications, debriefs and shared snapshots. Your account and plugin sign-in remain.
